摘要
泸沽湖是中国国家重要湿地,是云南众多候鸟越冬的重要栖息地之一。2012年10月至2013年3月在沿湖和竹地海子等地设置16个观察点进行6次野外调查,共记录到泸沽湖越冬水禽6目7科25种,占云南省已记录水鸟种类134种的18.66%,其中鸭科14种、秧鸡科2种、??科3种、鸥科1种、鹬科2种、鹤科1种及鹭科2种,数量最高达28 000多只;与历史数据相比,泸沽湖的越冬水禽在种类和数量上都有所增加。分析认为,旅游业的开展给当地水禽带来不利的影响,基础设施的建设导致湖滨浅水沼泽湿地丧失,食物可利用度下降导致水鸟种群数量下降。藉此,提出加强湿地的保护与管理,调整农作物结构,延长封湖禁渔期等保护泸沽湖越冬水禽的建议。
Lugu Lake is an important national wetland in China, also one of the most important habitats for many migratory birds wintering in Yunnan. Results of six field survey from Oct 2012 to Mar 2013 showed that there are wintering waterfowl of 6 orders 7 families 25 species in Lugu Lake, which account- ing for 18.66% of 134 waterfowl species recorded in Yunnan Province, including 14 species of anatidae, 2 species of rallidae, 3 species of grebe families, 1 species of gulls, 2 species of snipe, 1 families of crane and 2 species of ardeidae. The total mumbles are more than 28000. Compare with the historical da- ta, wintering waterfowl in Lugu Lake are increased in species and quantity. The analysis indicates that tourist trade, infrastructure construction and food availability are the main threats for waterfowl and habi- tat protection. Thereby, suggestions to reinforce protection and management, inspect structure of crop, extend fishing moratorium and so on are put forward.
